Windows 10: Is there any way to restore an old Minecraft Bedrock and Minecraft Java world after...

So I recently fully reset my PC and after I redownloaded Minecraft Bedrock Edition and Java edition, I saw that all my worlds were gone. So I was wondering if there was any way to get my old worlds back.

Is there a way to have my PS4 Minecraft Bedrock world available to play on PC Minecraft Bedrock?

Seeing as realms isnt a thing yet for PS4 minecraft bedrock, I was wondering if there was a way to put a world I have on PS4 bedrock onto my PC so I can play it on my PC.

How do I recover a corrupted Minecraft Bedrock world?

So here's the story. I was playing on one of my important minecraft worlds in Minecraft Windows 10 Edition, and I decide that I want to leave. So I open up the pause menu, and hit "Save and Quit". All is well, until in the middle of the saving and quitting
process, my computer gives me the Blue Screen of Death. Every now and then, I do get these, probably because I am using an older computer with Windows 10. But at the moment, that is not the point. What is important to me is that I get that Minecraft world
back. I was able to find that it indeed exists, but it won't show up in the world list. I have looked pretty much everywhere, but I could only find one or two things about recovering Minecraft Bedrock Edition worlds in particular. So, is there any way to recover
one for Minecraft Bedrock? And if so, would you please tell me? Also, for the record, I haven't made any backups of this world.
